Previously Privoxy would use the http headers which + may be empty on a reused connection. + - Make CGI_PREFIX protocol-relative when building with FEATURE_HTTPS_INSPECTION. + This unbreaks (at least) https://config.privoxy.org/client-tags whose + buttons would previously use a http:// URL resulting in browser warnings. + - Support using https-inspection and client-header-order at the same time. + Privously Privoxy would crash. + Reported by: Kai Raven + - Properly reject rewrites from http to https as they currently + aren't supported. Previously Privoxy would wait for the client + to establish an encrypted connection which obviously would not happen. + +- General improvements: + - Allow to rewrite the request destination for https-intercepted + requests behind the client's back. The documentation already sort + of claimed that it was supported by not especially mentioning that + it didn't work for https-inspected requests. + Fixes SF bug #923 reported by withoutname. + - Add support for filtering client request bodies by using + CLIENT-BODY-FILTER filters which can be enabled with the + client-body-filter action. + Patch submitted by Maxim Antonov. + Sponsored by: Robert Klemme + - Add the new action suppress-tag{} which can be used to prevent + a tagger from adding a tag. Patch submitted by Maxim Antonov. + Sponsored by: Robert Klemme + - Gracefully handle existing website keys without matching certificates. + This can happen if Privoxy was previously running with an invalid + TLS configuration that didn't allow it to create a certificate. + - Recycle debug bit 4 for Tagging-related messages. + - Improve the message shown when the client-tags CGI page + is requested with no tags configured. + - Shorten the 'donate' and 'participate' links used by templates + using redirects. Currently the redirects lead to the FAQ entries + but in the future we may want to relocate the content and using + redirects makes this more convenient. + - Log an error when a PCRE-HOST-PATTERN is used with + FEATURE_PCRE_HOST_PATTERNS disabled. Don't treat this a + fatal error so the regression tests can be used with and + without FEATURE_PCRE_HOST_PATTERNS. + - The code compiles with older C compilers again. + - Check the chdir() return code to fix a compiler warning. + - Let the crude-parental filter insert a link to Privoxy's webinterface. + - Remove the packages feed from the source tarball. + It's usually out of date when the source tarball is generated + for the release. + - Fix harmless compiler warnings from GCC9 with -D_FORTIFY_SOURCE=2. + - windows: Remove obsolete '$(DEST)/doc/images' target. + - windows: Install the images referenced in the user manual. + - Remove obsolete 'gnu_regex.@OBJEXT@' target. + - When installing from the GNUMAkefile, don't create an 'images' + directory which is no longer used. The images were relocated to + the user-manual directory years ago. + - Add new FEATURES to the show-status page and resort list. + - OpenSSL create_client_ssl_connection(): Remove unused variable. + - Update bug tracker URL in cgi_error_unknown(). + - Properly deal with host certificates without keys and keys without + host certificate which may be left over from a previous Privoxy run + with incorrect configuration. + - Saved a couple of memory allocations when sorting client headers. + - Improved a couple of error messages. + - Saved memory allocations when using OpenSSL and checking if a + key already exists. + - The configure script will bail out if OpenSSL and mbedTLS are + enabled at the same time. + - Log a message right before exiting gracefully. + +- Action file improvements: + - Block requests to eu-tlp03.kameleoon.com/. + - Unblock metrics.sr.ht/. + - Disable fast-redirects for .fsf.org/. + - Disable fast-redirects for .gravater.com/. + - Disable fast-redirects for .ksta.de/ + - Block requests to tag.crsspxl.com/. + - Block requests to analytics.slashdotmedia.com/. + - Block requests to ml314.com/. + - Block requests to .adroll.com/. + - Block requests to fastlane.rubiconproject.com/. + - Block requests to api.theadex.com/ + - Block requests to ih.adscale.de/ + - Block requests to .s400.meetrics.net/ + - Block requests for pp.lp4.io/ + +- Filter file improvements: + - Added new 'allow-autocompletion' filter which changes + autocomplete="off" to "on" on input fields to allow autocompletion. + Requested by Jamie Zawinski in #370. + Filter based on a submission by Aaron Linville. + - Added an imdb filter. + - Added a sourceforge filter that reduces the amount of ads + for proprietary software. + - Added a github filter that removes the annoying "Sign-Up" + banner and the Cookie disclaimer. + +- privoxy-log-parser: + - Highlight 'Rewritten request line results in downgrade to http'. + - Highlight 'Rewrite detected: ...' messages again. + - Add a handler for tagging messages. + - Bump version to 0.9.2. + - Properly deal with 'Certificate error' crunches + Previously the error description was highlighted as 'host'. + - Highlight: 'Flushed 3153 bytes of request body' + - Highlight 'The last 12078 bytes of the request body have been read' + - Highlight 'Sending data on socket 33 over TLS/SSL failed: ...' + - Log truncated LOG_LEVEL_CLF messages more gracefully + and note that the statistics will be inprecise. + +- privoxy-regression-test: + - Use http://127.0.0.1:8118/ as default privoxy address + unless http_proxy is set through the environment. + - Add a --privoxy-cgi-prefix option that specifies the prefix + to use when building URLs that are supposed to reach Privoxy's + CGI interface. If it's not set, http://p.p/ is used, which is + supposed to work with the default Privoxy configuration. + If Privoxy has been built with FEATURE_HTTPS_INSPECTION enabled, + and if https inspection is activated with the +https-inspection + action, this option can be used with "https://p.p/" provided the + system running Privoxy-Regression-Test has been configured to + trust the certificate used by Privoxy. + Note that there are currently two tests in the official + regression-tests.action file that are expected to fail + when using "https://p.p/" as privoxy-cgi-prefix. + - Skip the connection-established response in get_status_code() + when looking for the status code with a CGI prefix + that starts with https://. We care about the status code + sent by the impersonated web server. + - Use --proxy-header when using a CGI prefix with https:// + and a "Host:" header. + - Allow '|' in tokens and values to allow tag patterns like + "TAG:^(application|text)/(x-)?javascript$". + - When get_cgi_page_or_else() fails, include the URL of the + requested page in the log message. + - privoxy-regression-test: Bump version to 0.7.2 + +- uagen: + - Update example output. + - Recommend the use of the https-inspection action in the documentation. + - Upgrade a couple of URLs to https://. + - Add ElectroBSD to the list of operating systems. + - Bump generated Firefox version to 78 (ESR). + - Bump version to 1.2.2. + + - User Documentation: + - Remove reference to 'How to Report Bugs Effectively'. + It was only rendered as text without URL in the README anyway + and there's no indication that users read it ... + - Let the dok-readme target fix the location embedded into the + README file. This used to be done by CVS but since the git migration + it has to be done through other means. + - Remove 'experimental' warning for client-specific-tag-related directives. + They seem to work reliably and there is no obvious reason + why we would change the syntax in the near future. + - Describe how to check if Privoxy has been built with + FEATURE_HTTPS_INSPECTION. + - Add a link to the trusted-cas-file documentation + that explains how the user can create the file herself. + - Don't explicitly mention the license for the code coming from + 'Anonymous Coders' and Junkbusters. It's obviously licensed under + the GNU GPL like the rest of Privoxy or we wouldn't be allowed to + distribute it. + - Update the +hide-user-agent example with uagen output. + - Slightly improve the wording of the ca-key-file documentation. + - Explicitly mention Windows 10 as supported so search engines and + users looking for it can find it. + - Import a bunch of contributors from the ChangeLog. + - Remove obsolete doc/gpl.html. + - Upgrade a couple of links to https://. + - Don't prefer the SourceForge patch tracker over the + privoxy-devel mailing list. While at it, link to the + SourceForge patch tracker. + - Mention http-inspection in the 'my browser warns me about + unauthenticated content' FAQ entry. + - Simplify the 'Is there is a license or fee?' FAQ entry. + - Add another +redirect{} example. + - Explicitly mention that interested sponsors should include + the link target in their first mail. + - Clarify that only Privoxy team members can object to new sponsors + and link to the list of current team members. + - Note that sponsor URLs may not contain keyword spam. + - Garbage collect doc/webserver/images which isn't referenced anymore. + - Update the method to reach the proxy settings in Firefox. + - Update proxy_setup.jpg description to refer to Firefox. + - Regenerate proxy_setup.jpg with a more recent Firefox (78.0). + - Regenerate files-in-use.jpg without obsolete standard.action + with modern colors and a slightly better quality. + - Update URL to the actionsfile tracker. + - Update a support request URL. + - Rephrase the 'Can Privoxy run as service' FAQ entry and + remove an obsolete paragraph. + - Let the 'Where can I get updated Actions Files?' entry link to + the gitweb version of default.action.master. + - Update a link to the default.action file. + - Update URLs for trackers and mailing lists. + - Replace CVS reference with git. + - Mention regression-tests.action in the config file. + - Explicitly mention in the config file that access to the + ca key should be limited to Privoxy. + - List more client-specific-tag examples for inspiration. + - Add additional headers to the client-header-order example. + - Note that actions aren't updated after rewrites. + - Explicitly mention that upgrading from http to https with + a client-header filter is not supported + - Note that protocol and host have to be added when rewriting + the destination host for https-inspected requests. + - Explicitly mention that the CA key is used to sign certificates. + +- Developer Manual: + - Flesh out the build instructions for Debian. + - Remove the packaging instructions for RPM-based systems. + They don't work and we don't release RPM packages anymore anyway. + - Remove the packaging instructions for Solaris. + They don't work and we don't release Solaris packages anymore anyway. + - Update the suggested subject for the announce mails. + - Update upload instructions. + ftp://upload.sourceforge.net is no longer functional. + - Remove a couple of package-dependent upload instructions + that don't actually work. + - Remove 'cd current' that no longer works. + - Add regression-tests.action to the list of files that should be installed. + - Stop claiming that there are text versions of the manuals. + We stopped building them in 2008 (9ed36a3c5e6f12). + - Note that the 'webserver' target creates the link needed for the user-manual. + - Suggest to use the master branch as reference when creating + the ChangeLog so the steps work when the current branch differs + from master which is likely as the developer manual + suggests to use a local branch for development. + - Add the -s flag to the suggested 'git tag' command. We prefer signed tags. + - Mention that merges into 'master' should be avoided. + - Add git commands that should result in a merge-free history. + - Mention Privoxy-Regression-Test. + - Add a section id to reduce link churn. + - Recommend the dok-tidy target when building docs for the webserver. + - Add another plug for the privoxy-devel mailing list. + - Let the intro link the copyright section in the user manual instead + of giving an incomplete summary of the license status. + - Clarify that the webserver target uploads to the SourceForge webserver. + - Mark the documentation for the Mac OS X installers as out of date and + change the SCM name back to CVS. + - Fix the location of the installer modules for Mac OS X. + They are not actually available through git (yet). + - Don't speak of Privoxy version 3 in the past tense. + - Update the list of programs required for the release process. + - Put openssl command in 'command' tags. + - Update description of the webserver target which uses ssh, not scp. + - Remove obsolete reference to config.new. + +- Tests: + - Add another hide-referrer{conditional-block} test. + - Add another hide-referrer{conditional-forge} test. + - Fix a hide-referrer{conditional-forge} test + that expected an acceptable header to be forged. + - Fix a hide-referrer{conditional-block} test + that expected an acceptable Referer to be removed. + - Explain why the "Set Header = Host: whatever.example.org" test is + expected to fail when using a CGI prefix that starts with "https://". + - Explain why a connection-sharing test is known to fail + when using "https://p.p/" as CGI prefix. + - Add a link to Privoxy-Regression-Test to regression-tests.action + in case it isn't packaged. + - Add regression tests for pcre host patterns. + +- Privoxy Infrastructure: + - Import a Privoxy logo for the website. + - Update Tor onion service to HiddenServiceVersion 3. + - Display the "model" photos in a single row and remove placeholder images. + - Regenerate homepage with updated sponsor list. + - Use the '/sponsor' redirect for the link to the sponsor page. + - Git commit messages are sent to the Privoxy-commits mailing list. + +*** Version 3.0.29 stable *** + +- Security/Reliability: + - Fixed memory leaks when a response is buffered and the buffer + limit is reached or Privoxy is running out of memory. + Commits bbd53f1010b and 4490d451f9b. OVE-20201118-0001. + Sponsored by: Robert Klemme + - Fixed a memory leak in the show-status CGI handler when + no action files are configured. Commit c62254a686. + OVE-20201118-0002. + Sponsored by: Robert Klemme + - Fixed a memory leak in the show-status CGI handler when + no filter files are configured. Commit 1b1370f7a8a. + OVE-20201118-0003. + Sponsored by: Robert Klemme + - Fixes a memory leak when client tags are active. + Commit 245e1cf32. OVE-20201118-0004. + Sponsored by: Robert Klemme + - Fixed a memory leak if multiple filters are executed + and the last one is skipped due to a pcre error. + Commit 5cfb7bc8fe. OVE-20201118-0005. + - Prevent an unlikely dereference of a NULL-pointer that + could result in a crash if accept-intercepted-requests + was enabled, Privoxy failed to get the request destination + from the Host header and a memory allocation failed. + Commit 7530132349. CID 267165. OVE-20201118-0006. + - Fixed memory leaks in the client-tags CGI handler when + client tags are configured and memory allocations fail. + Commit cf5640eb2a. CID 267168. OVE-20201118-0007. + - Fixed memory leaks in the show-status CGI handler when memory + allocations fail. Commit 064eac5fd0 and commit fdee85c0bf3. + CID 305233. OVE-20201118-0008. + +- General improvements: + - Added experimental https inspection support which allows to filter + https traffic. To enable it, install MbedTLS and configure with + --with-mbedtls, or install OpenSSL or LibreSSL and configure + with --with-openssl. + Afterwards configure the directives in section 7 of the + config file and enable the +https-inspection action. + Initial MbedTLS-based code contributed by Vaclav Svec, + initial OpenSSL support contributed by Maxim Antonov. + With help from Nedzad Hrnjica and Ho+ Ho+ Ho+. + Integration and improvements sponsored by Robert Klemme. + - pcrs: Request JIT compilation if it's supported and + the filter isn't dynamic. This can speed up filtering. + - Added support for Brotli decompression. + Sponsored by: Robert Klemme + - Added FEATURE_EXTENDED_STATISTICS to gather statistics for + block reasons and filter executions. To enable it, configure + with --enable-extended-statistics and visit + http://config.privoxy.org/show-status. + Sponsored by: Robert Klemme + - Use the IP_FREEBIND socket option, if defined. This allows + Privoxy to bind to not-yet assigned IP addresses which is + useful in failover environments. + Patch by Sam Varshavchik. + - Allow to use extended host patterns and vanilla host patterns + at the same time by prefixing extended host patterns with + "PCRE-HOST-PATTERN:". To enable this, configure with + --enable-pcre-host-patterns. + Sponsored by: Robert Klemme + - Added "Cross-origin resource sharing" (CORS) support. + This allows to access Privoxy's CGI interface via JavaScript from + another domain (white-listed with the new cors-allowed-origin directive). + Based on a patch by Nedzad Hrnjica. + Sponsored by: Robert Klemme. + - Add SOCKS5 username/password support. + Based on a patch by Sam, improved by Ivan Romanov. + Closes Patch#141 and solves TODO#105. + - Bump the maximum number of action and filter files + to 100 each. + Sponsored by: Robert Klemme + - Fixed handling of filters with "split-large-forms 1" + when using the CGI editor. + Reported by withoutname in #921. + - Better detect a mismatch of connection details when + figuring out whether or not a connection can be reused. + - Don't send a "Connection failure" message instead of the + "DNS failure" message. + Sponsored by: Robert Klemme + - Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted + requests were only logged with LOG_LEVEL_REQUEST when they weren't + crunched (in which case they were logged with LOG_LEVEL_CRUNCH). + This was documented behaviour, but logging all requests seems more useful. + - Fixed locking around localtime() and gmtime(). + - Removed OS/2 support. We haven't provided OS/2 packages in years, + it complicated the code and it depended on a fallback snprintf() + implementation which is GPLv2 only. + - Remove the fallback snprintf() implementation + Now that OS/2 support is gone we no longer need it. + - Fixed a bunch of format specifiers log messages. + - Added a missing apostrophe in the 'More Privoxy' menu. + - Explicitly prevent use of FEATURE_CONNECTION_SHARING + without FEATURE_CONNECTION_KEEP_ALIVE. It makes no sense + and does not compile anyway. + Sponsored by: Robert Klemme + - Fix build without FEATURE_CONNECTION_KEEP_ALIVE. + Sponsored by: Robert Klemme + - Downgrade the 'Graceful termination requested' message + to LOG_LEVEL_INFO as it isn't an error. + Sponsored by: Robert Klemme + - decompress_iob(): Downgrade the no-content message to LOG_LEVEL_RE_FILTER + While at it, fix a typo in a comment. + Sponsored by: Robert Klemme + - Fixed a couple of cppcheck warnings. + - Rename LOG_LEVEL_GPC to LOG_LEVEL_REQUEST. + Only the shadow knows what "GPC" is supposed to stand for. + - Remove SourceForge references in copyright headers. + - Upgrade a bunch of links to the homepage to https://. + - Add 'no-brotli-accepted' filter which prevents the + use of Brotli compression. + - Changed license for pcrs to GPLv2+ after getting the + permission from Andreas. This allows to redistribute + Privoxy under the GPLv3 which is required when linking + to future mbedTLS versions which are expected to be + licensed under the Apache 2.0 license only. + - Updated a bunch of tests that have to expect status code 403 + now after r1.168/070e904afa5. + - Lowercase the host name in the request line. + - Only set SOURCE_DATE_EPOCH if it's not already set so + distributions can overwrite it through the environment. + +- Documentation changes: + - Explain that Privoxy has to be distributed under the + GPLv3 (or later) when linked with an MbedTLS version + that is licensed under the Apache 2.0 license. + - Import the GNU GPLv3 and include it the user manual. + - Clarify FEATURE_FORCE_LOAD's description. It allows to bypass + blocking not filtering and only does it if blocks aren't enforced. + Reported by: Robert Klemme + - FAQ: Remove Zwiebelfreunde e.V. from the list of fiduciary sponsors + As of 2021 they no longer handle donations for foreign organisations + due to lack of resources. + - FAQ: Remove an obsolete comment with a link to the long-gone PDF manual. + - FAQ: Add a link to the TODO list. + - FAQ: Change the sponsor amounts to USD slightly rounding the + converted amounts up to get simple numbers. + Receiving USD is apparently easier for SPI and SPI is + preferred by sponsors as they can send invoices. + - Advertise the client-tags CGI page in the user manual. + - Stop advertising the show-version CGI page which no longer exists. + - Add yet another reason why +prevent-compression may cause problems. + - Don't claim that contributors need ssh. It's only needed for committers. + - Replace obsolete CVS instructions with Git instructions. + - Remove an obsolete comment + +- Config file changes: + - Change the suggested default-server-timeout to 5 to match the + suggested keep-alive-timeout. Otherwise using the defaults would + result in Privoxy reducing the default-server-timeout and logging + an error message. + Sponsored by: Robert Klemme + - Update the 'debug 1' description. + - Add a missing 'client-specific-tag' directive. + - Comment out trusted-cgi-referer pointing to example.org. + +- Action file improvements: + - Block requests to /(.*/)?piwik\.php + - Block requests to .connectaserver.de/ + - Block requests to pixel.inforsea.com/ + - Block requests to t.vi-serve.com/ + - Block requests to .ioam.de/ + - Block requests to t.9gag.com/img.gif + - Block requests to .pixel.parsely.com/ as image + - Block requests to pixel.wp.com/ + - Disable fast-redirects for .librarything.com/ + - Disable fast-redirects for issue.freebsdfoundation.org/ + - Disable fast-redirects for .twitter.com/.*origin=http + - Unblock belco24.de/ + - Add fast-redirects exception for .wikipedia.org/ + - Add fast-redirects exception for oss-fuzz.com/ + - Disable fast-redirects for .consensu.org/delivery/pixel\.php + and block the requests as image instead + - Unblock .adbinstaller.com/ + Reported by lvm in #942. + - Unblock .adbshell.com + Reported by lvm in #942. + - Unblock .tagesschau.de/ + - Disable fast-redirects for collector.githubapp.com/ + and block requests to it as image instead + - Unblock 'ada*.' + - Add fast-redirects{} exception for sourcepoint.vice.com/ + - Unblock adaway.org/ + Reported by DRS David Soft in AF#945. + - Change two block reasons that previously were the same. + Sponsored by: Robert Klemme + - Added a +delay-response{} test. + - Updated the location of the development version + of default.action.master. + +- Privoxy-Log-Parser: + - Added a --keep-date option to keep the date in highlighted messages. + - Highlight new log messages. + - Make gather_loglevel_clf_stats() more tolerant. While at it, + count all CLF messages as requests, even if the request is invalid. + - Only show HTTP version distribution if at least one version has been detected. + - Only show crunch statistics if crunches were detected. + - Warn if the request counts differ. + - Generate statistics if the log only contains LOG_LEVEL_CLF messages + so it can be used with vanilla webserver logs. + Previously Privoxy-specific "Request:" messages were required. + - Align the client-HTTP-version distribution like other distributions + - Bump version to 0.9.1 + - Include status code distribution in the stats. + - Let the statistics include the size of the content Privoxy + transferred excluding HTTP headers. + - Get with the program and expect all requests to be logged with LOG_LEVEL_REQUEST. + It's no longer necessary to count both LOG_LEVEL_REQUEST and + LOG_LEVEL_CRUNCH messages to get the total number of requests. + - Leverage the LOG_LEVEL_CLF message to gather statistics that where + previously taken from LOG_LEVEL_HEADER lines. This results in less + confusing results if https inspection is enabled in which case there + are two LOG_LEVEL_HEADER lines with request lines. + Sponsored by: Robert Klemme + - Properly highlight the filter results message. Previously a brace got lost. + - Prefer the number of CLF lines to get the total number of requests + as it works with older Privoxy versions as well. + +- Privoxy-Regression-Test: + - Turn curl's globbing mode off so we can allow more characters in URLs. + - Allow '[' and ']' in URLs. + - Include the action file when complaining about missing Sticky Actions. + - Fix a sentence in the documentation. + - Bump version to 0.7.1 + +- url-pattern-translator: + - Detect a couple of pattern prefixes case-insensitively. + Sponsored by: Robert Klemme + - Skip CLIENT-TAG patterns. + Sponsored by: Robert Klemme + - Skip patterns that have already been converted. + It should now be safe to "convert" a file multiple times. + Sponsored by: Robert Klemme + - Add the new 'PCRE-HOST-PATTERN:' prefix. + Sponsored by: Robert Klemme + +*** Version 3.0.28 stable *** + +- Bug fixes for regressions in 3.0.27: + - Fixed misplaced parentheses. + Reported by David Binderman. + - Changed two regression tests to depend on config directive + enable-remote-toggle instead of FEATURE_TOGGLE. + +*** Version 3.0.27 stable *** + +- General improvements: + - Add a receive-buffer-size directive which can be used to + set the size of the previously statically allocated buffer + in handle_established_connection(). + Increasing the buffer size increases Privoxy's memory usage but + can lower the number of context switches and thereby reduce the + CPU usage and potentially increase the throughput. + This is mostly relevant for fast network connections and + large downloads that don't require filtering. + Sponsored by: Robert Klemme + - Add a listen-backlog directive which specifies the backlog + value passed to listen(). + Sponsored by: Robert Klemme + - Add an enable-accept-filter directive which allows to + toggle accept filter support at run time when compiled + with FEATURE_ACCEPT_FILTER support. + It makes testing more convenient and now that it's + optional we can emit an error message if enabling + the accept filter fails. + Sponsored by: Robert Klemme + - Add a delay-response{} action. + This is useful to tar pit JavaScript requests that + are endlessly retried in case of blocks. It can also + be used to simulate a slow Internet connection. + Sponsored by: Robert Klemme + - Add a 'trusted-cgi-referrer' directive. + It allows to configure another page or site that can be used + to reach sensitive CGI resources. + Sponsored by: Robert Klemme + - Add a --fuzz mode which exposes Privoxy internals to input + from files or stdout. + Mainly tested with American Fuzzy Lop. For details see: + https://www.fabiankeil.de/talks/fuzzing-on-freebsd/ + This work was partially funded with donations and done + as part of the Privoxy month in 2015. + - Consistently use the U(ngreedy) flag in the 'img-reorder' filter. + - listen_loop(): Reuse a single thread attribute object + The object doesn't change and creating a new one for + every thread is a waste of (CPU) time. + Sponsored by: Robert Klemme + - Free csp resources in the thread that belongs to the csp instead + of the main thread which has enough on its plate already. + Sponsored by: Robert Klemme + - Improve 'socket timeout reached' message. + Log the timeout that was triggered and downgrade the + log level to LOG_LEVEL_CONNECT to reduce the log noise + with common debug settings. + The timeout isn't necessary the result of an error and + usually merely indicates that Privoxy's socket timeout + is lower than the relevant timeouts used by client and + server. + Sponsored by: Robert Klemme + - Explicitly taint the server socket in case of CONNECT requests. + This doesn't fix any known problems, but makes + some log messages less confusing. + - Let write_pid_file() terminate if the pid file can't be opened. + Logging the issue at info level is unlikely to help. + - log_error(): Reduce the mutex-protected area by not using a + heap-allocated buffer that is shared between all threads. + This increases performance and reduces the latency with + verbose debug settings and multiple concurrent connections. + Sponsored by: Robert Klemme + - Let zalloc() use calloc() if it's available. + In some situations using calloc() can be faster than + malloc() + memset() and it should never be slower. + In the real world the impact of this change is not + expected to be noticeable. + Sponsored by: Robert Klemme + - Never use select() when poll() is available. + On most platforms select() is limited by FD_SETSIZE while + poll() is not. This was a scaling issue for multi-user setups. + Using poll() has no downside other than the usual risk + that code modifications may introduce new bugs that have + yet to be found and fixed. + At least in theory this commit could also reduce the latency + when there are lots of connections and select() would use + "bit fields in arrays of integers" to store file descriptors. + Another side effect is that Privoxy no longer has to stop + monitoring the client sockets when pipelined requests are + waiting but can't be read yet. + This code keeps the select()-based code behind ifdefs for + now but hopefully it can be removed soonish to make the + code more readable. + Sponsored by: Robert Klemme + - Add a 'reproducible-tarball-dist' target. + It's currently separate from the "tarball-dist" target + because it requires a tar implementation with mtree spec + support. + It's far from being perfect and does not enforce a + reproducible mode, but it's better than nothing. + - Use arc4random() if it's available. + While Privoxy doesn't need high quality pseudo-random numbers + there's no reason not to use them when we can and this silences + a warning emitted by code checkers that can't tell whether or not + the quality matters. + - Show the FEATURE_EXTERNAL_FILTERS status on the status page. + Better late than never. Previously a couple of tests weren't + executed as Privoxy-Regression-Test couldn't detect that the + FEATURE_EXTERNAL_FILTERS dependency was satisfied. + - Ditch FEATURE_IMAGE_DETECT_MSIE. + It's an obsolete workaround we inherited from Junkbuster + and was already disabled by default. + Users that feel the urge to work around issues with + image requests coming from an Internet Explorer version + from more than 15 years ago can still do this using tags. + - Consistently use strdup_or_die() instead of strdup() in + cases where allocation failures aren't expected. + Using strdup_or_die() allows to remove a couple of explicit + error checks which slightly reduces the size of the binary. + - Insert a refresh tag into the /client-tags CGI page when + serving it while a client-specific tag is temporarily enabled. + This makes it less likely that the user ends up + looking at tag state that is out of date. + - Use absolute URLs in the client-tag forms. + It's more consistent with the rest of the CGI page + URLs and makes it more convenient to copy the forms + to external pages. + - cgi_error_disabled(): Use status code 403 and an appropriate response line + - Use a dedicated CGI handler to deal with tag-toggle requests + As a result the /client-tags page is now safe to reach without + trusted Referer header which makes bookmarking or linking to + it more convenient. + Finally, refreshing the /client-tags page to show the + current state can no longer unintentionally repeat the + previous toggle request. + - Don't add a "Connection" header for CONNECT requests. + Explicitly sending "Connection: close" is not necessary and + apparently it causes problems with some forwarding proxies + that will close the connection prematurely. + Reported by Marc Thomas. + - Fix compiler warnings. + +- Bug fixes: + - rfc2553_connect_to(): Properly detect and log when poll() + reached the time out. Previously this was logged as: + Could not connect to [...]: No error: 0. + which isn't very helpful. + Sponsored by: Robert Klemme + - add_tag_for_client(): Set time_to_live properly. + Previously the time_to_live was always set for the first tag. + Attempts to temporarily enable a tag would result in enabling + it permanently unless no tag was enabled already. + - Revert r1.165 which didn't perform as advertised. + While the idea was to use "https:// when creating links + for the user manual on the website", the actual effect + was to use "https://" when Privoxy was supposed to serve + the user manual itself. + Reported by Yossi Zahn on Privoxy-devel@. + - socks5_connect(): Fail in case of unsupported address types. + Previously they would not be detected right away and + Privoxy would fail later on with an error message that + didn't make it obvious that the problem was socks-related. + So far, no such problems have actually been reported. + - socks5_connect(): Properly deal with socks replies that + contain IPv6 addresses. + Previously parts of the reply were left unread and + later on treated as invalid HTTP response data. + Fixes #904 reported by Danny Goossen who also provided + the initial version of this patch. + +- Action file improvements: + - Unblock 'msdn.microsoft.com/'. + It (presumably) isn't used to serve the kind of ads Privoxy should + block by default but happens to serve lots of pages with URLs that + are likely to result in false positives. + Reported by bugreporter1694 in AF#939. + - Disable gif deanimation for requests tagged with CSS-REQUEST. + The action will ignore content that isn't considered text + anyway and explicitly disabling it makes this more obvious + if "action" debugging (debug 65536) is enabled while + "gif deanimation" debugging (debug 256) isn't. + - Explicitly disable HTML filters for requests with CSS-REQUEST tag. + The filters are unlikely to break CSS files but executing + them without (intentionally) getting any hits is a waste of + cpu time and makes the log more noisy when running with + "debug 64". + - Unblock 'adventofcode.com/'. + Reported by Clint Adams in Debian bug #848211. + Fixes Roland's AF#937. + - Unblock 'adlibris.com'. + Reported by Wyrex in #935 + - Unblock .golang.org/ + - Add fast-redirects exception for '.youtube.com/.*origin=http' + +- Privoxy-Log-Parser: + - Don't gather host and resource statistics if they aren't requested. + While the performance impact seems negligible this significantly + reduces the memory usage if there are lots of requests. + - Bump version as the behaviour (slightly) changed. + - Count connection failures as well in statistics mode. + Sponsored by: Robert Klemme + - Count connection timeouts as well in statistics mode. + Sponsored by: Robert Klemme + - Fix an 'uninitialized value' warning when generating + statistics for a log file without response headers. + While privoxy-log-parser was supposed to detect this already, + the check was flawed and the message the user didn't see was + somewhat confusing anyway. + Now the message is less confusing, more helpful and actually printed. + Reported by: Robert Klemme + +- Documentation improvements: + - Refer to the git sources instead of CVS. + - Use GNU/Linux when referring to the OS instead of the kernel. + - Add FAQ entry for what to do if editing the config file is access denied. + - Add brief HTTP/2 FAQ. + - Add a small fuzzing section to the developer documentation. + - Add a client-header-tagger{client-ip-address} example. + - Stop suggesting that Privoxy is an anonymizing proxy. + The term could lead to Privoxy users overestimating + what it can do on its own (without Tor). + - Make it more obvious that SPI accepts Paypal, too. + Currently most donations are made through the Paypal account + managed by Zwiebelfreunde e.V. and a more even distribution + would be useful. + - Suggest to log applying actions as well when reproducing problems. + - Explicitly mention that Privoxy binaries are built by individuals + on their own systems. Buyer beware! + - Mention the release feed on the homepage. + - Remove a mysterious comment with a GNU FDL link as it isn't + useful and could confuse license scanners. + In May 2002 it was briefly claimed that "this document" was covered + by the GNU FDL. The commit message (r1.5) doesn't explain the motivation + or whether all copyright holders were actually asked and agreed to the + declared license change. + It's thus hard to tell whether or not the license change was legit, + but luckily two days later the "doc license" was "put" "back to GPL" + anyway (r1.6). + At the same time the offending comment with a link to the FDL + (not the GPL) was added for no obvious reason. + Now it's gone again. + +- Regression tests: + - Bump for-privoxy-version to 3.0.27 as we now rely on untrusted + CGI request being rejected with status code 403 (instead of 200). + - Update test for /send-stylesheet and add another one + +- Templates: + - Consistently use https:// when linking to the Privoxy website. + - Remove SourceForge references in Copyright header. + - Remove a couple of SourceForge references in a comment. + While at it, fix the grammar. + - Move the site-specific documentation block before the generic one. + While most Privoxy installations don't have a site-specific + documentation block, in cases were it exists it's likely to + be more relevant than the generic one. + Showing it first makes it less likely that users stop reading + before they reach it, especially on pages that don't fit on + the screen. + +- Build system improvements: + - Prefer openjade to jade. On some systems Jade produces + HTML with unescaped ampersands in URLs. + - Prefer OpenSP to SP to be consistent. + - Have Docbook generated HTML files be straight ASCII. + Dealing with a mixture of ISO-8859 and UTF-8 files is problematic. + - Echo the filename to stderr for 'make dok-tidy'. + Make it a bit easier to find errors in docbook generated HTML. + - Warn when still using select(). + - Warn when compiling without calloc(). + - Make it more obvious that the --with-fdsetsize configure switch + is pointless if poll() is available. + - Remove support for AmigaOS. + - Update windows build system to use supported software. + The cygwin gcc -mno-cygwin option is no longer supported, so + convert the windows build system to use the cygwin cross-compiler + to build "native" code. + - Add --enable-static-linking option for configure + does the same thing as LDFLAGS=-static; ./configure + but nicer than mixing evars and configure options. + +*** Version 3.0.26 stable *** + +- Bug fixes: + - Fixed crashes with "listen-addr :8118" (SF Bug #902). + The regression was introduced in 3.0.25 beta and reported + by Marvin Renich in Debian bug #834941. + +- General improvements: + - Log when privoxy is toggled on or off via cgi interface. + - Highlight the "Info: Now toggled " on/off log message + in the Windows log viewer. + - Highlight the loading actions/filter file log message + in the Windows log viewer. + - Mention client-specific tags on the toggle page as a + potentionally more appropriate alternative. + +- Documentation improvements: + - Update download section on the homepage. + The downloads are available from the website now. + - Add sponsor FAQ. + - Remove obsolete reference to mailing lists hosted at SourceForge. + - Update the "Before the Release" section of the developer manual. + +- Infrastructure improvements: + - Add perl script to generate an RSS feed for the packages + Submitted by "Unknown". + +- Build system improvements: + - strptime.h: fix a compiler warning about ambiguous else. + - configure.in: Check for Docbook goo on the BSDs as well. + - GNUMakefile.in: Let the dok-user target remove temporary files. + +*** Version 3.0.25 beta *** + +- Bug fixes: + - Always use the current toggle state for new requests. + Previously new requests on reused connections inherited + the toggle state from the previous request even though + the toggle state could have changed. + Reported by Robert Klemme. + - Fixed two buffer-overflows in the (deprecated) static + pcre code. These bugs are not considered security issues + as the input is trusted. + Found with afl-fuzz and ASAN. + +- General improvements: + - Added support for client-specific tags which allow Privoxy + admins to pre-define tags that are set for all requests from + clients that previously opted in through the CGI interface. + They are useful in multi-user setups where admins may + want to allow users to disable certain actions and filters + for themselves without affecting others. + In single-user setups they are useful to allow more fine-grained + toggling. For example to disable request blocking while still + crunching cookies, or to disable experimental filters only. + This is an experimental feature, the syntax and behaviour may + change in future versions. + Sponsored by Robert Klemme. + - Dynamic filters and taggers now support a $listen-address variable + which contains the address the request came in on. + For external filters the variable is called $PRIVOXY_LISTEN_ADDRESS. + Original patch contributed by pursievro. + - Add client-header-tagger 'listen-address'. + - Include the listen-address in the log message when logging new requests. + Patch contributed by pursievro. + - Turn invalid max-client-connections values into fatal errors. + - The show-status page now shows whether or not dates before 1970 + and after 2038 are expected to be handled properly. + This is mainly useful for Privoxy-Regression-Test but could + also come handy when dealing with time-related support requests. + - On Mac OS X the thread id in log messages are more likely to + be unique now. + - When complaining about missing filters, the filter type is logged + as well. + - A couple of harmless coverity warnings were silenced + (CID #161202, CID #161203, CID #161211). + +- Action file improvements: + - Filtering is disabled for Range requests to let download resumption + and Windows updates work with the default configuration. + - Unblock ".ardmediathek.de/". + Reported by ThTomate in #932. + +- Documentation improvements: + - Add FAQ entry for crashes caused by memory limits. + - Remove obsolete FAQ entry about a bug in PHP 4.2.3. + - Mention the new mailing lists were appropriate. + As the archives have not been migrated, continue to + mention the archives at SF in the contacting section + for now. + - Note that the templates should be adjusted if Privoxy is + running as intercepting proxy without getting all requests. + - A bunch of links were converted to https://. + - Rephrase onion service paragraph to make it more obvious + that Tor is involved and that the whole website (and not + just the homepage) is available as onion service. + - Streamline the "More information" section on the homepage further + by additionally ditching the link to the 'See also' section + of the user manual. The section contains mostly links that are + directly reachable from the homepage already and the rest is + not significant enough to get a link from the homepage. + - Change the add-header{} example to set the DNT header + and use a complete section to make copy and pasting + more convenient. + Add a comment to make it obvious that adding the + header is not recommended for obvious reasons. + Using the DNT header as example was suggested by + Leo Wzukw. + - Streamline the support-and-service template + Instead of linking to the various support trackers + (whose URLs hopefully change soon), link to the + contact section of the user manual to increase the + chances that users actually read it. + - Add a FAQ entry for tainted sockets. + - More sections in the documentation have stable URLs now. + - FAQ: Explain why 'ping config.privoxy.org' is not expected + to reach a local Privoxy installation. + - Note that donations done through Zwiebelfreunde e.V. currently + can't be checked automatically. + - Updated section regarding starting Privoxy under OS X. + - Use dedicated start instructions for FreeBSD and ElectroBSD. + - Removed release instructions for AIX. They haven't been working + for years and unsurprisingly nobody seems to care. + - Removed obsolete reference to the solaris-dist target. + - Updated the release instructions for FreeBSD. + - Removed unfinished release instructions for Amiga OS and HP-UX 11. + - Added a pointer to the Cygwin Time Machine for getting the last release of + Cygwin version 1.5 to use for building Privoxy on Windows. + - Various typos have been fixed. + +- Infrastructure improvements: + - The website is no longer hosted at SourceForge and + can be reached through https now. + - The mailing lists at SourceForge have been deprecated, + you can subscribe to the new ones at: https://lists.privoxy.org/ + - Migrating the remaining services from SourceForge is + work in progress (TODO list item #53). + +- Build system improvements: + - Add configure argument to optimistically redefine FD_SETSIZE + with the intent to change the maximum number of client + connections Privoxy can handle. Only works with some libcs. + Sponsored by Robert Klemme. + - Let the tarball-dist target skip files in ".git". + - Let the tarball-dist target work in cwds other than current. + - Make the 'clean' target faster when run from a git repository. + - Include tools in the generic distribution. + - Let the gen-dist target work in cwds other than current. + - Sort find output that is used for distribution tarballs + to get reproducible results. + - Don't add '-src' to the name of the tar ball generated by the + gen-dist target. The package isn't a source distribution but a + binary package. + While at it, use a variable for the name to reduce the chances + that the various references get out of sync and fix the gen-upload + target which was looking in the wrong directory. + - Add regression-tests.action to the files that are distributed. + - The gen-dist target which was broken since 2002 (r1.92) has been fixed. + - Remove genclspec.sh which has been obsolete since 2009. + - Remove obsolete reference to Redhat spec file. + - Remove the obsolete announce target which has been commented out years ago. + - Let rsync skip files if the checksums match. + +- Privoxy-Regression-Test: + - Add a "Default level offset" directive which can be used to + change the default level by a given value. + This directive affects all tests located after it until the end + of the file or a another "Default level offset" directive is reached. + The purpose of this directive is to make it more convenient to skip + similar tests in a given file without having to remove or disable + the tests completely. + - Let test level 17 depend on FEATURE_64_BIT_TIME_T + instead of FEATURE_PTHREAD which has no direct connection + to the time_t size. + - Fix indentation in perldoc examples. + - Don't overlook directives in the first line of the action file. + - Bump version to 0.7. + - Fix detection of the Privoxy version now that https:// + is used for the website. + +*** Version 3.0.24 stable *** + +- Security fixes (denial of service): + - Prevent invalid reads in case of corrupt chunk-encoded content. + CVE-2016-1982. Bug discovered with afl-fuzz and AddressSanitizer. + - Remove empty Host headers in client requests. + Previously they would result in invalid reads. CVE-2016-1983. + Bug discovered with afl-fuzz and AddressSanitizer. + +- Bug fixes: + - When using socks5t, send the request body optimistically as well. + Previously the request body wasn't guaranteed to be sent at all + and the error message incorrectly blamed the server. + Fixes #1686 reported by Peter Müller and G4JC. + - Fixed buffer scaling in execute_external_filter() that could lead + to crashes. Submitted by Yang Xia in #892. + - Fixed crashes when executing external filters on platforms like + Mac OS X. Reported by Jonathan McKenzie on ijbswa-users@. + - Properly parse ACL directives with ports when compiled with HAVE_RFC2553. + Previously the port wasn't removed from the host and in case of + 'permit-access 127.0.0.1 example.org:80' Privoxy would try (and fail) + to resolve "example.org:80" instead of example.org. + Reported by Pak Chan on ijbswa-users@. + - Check requests more carefully before serving them forcefully + when blocks aren't enforced. Privoxy always adds the force token + at the beginning of the path, but would previously accept it anywhere + in the request line. This could result in requests being served that + should be blocked. For example in case of pages that were loaded with + force and contained JavaScript to create additionally requests that + embed the origin URL (thus inheriting the force prefix). + The bug is not considered a security issue and the fix does not make + it harder for remote sites to intentionally circumvent blocks if + Privoxy isn't configured to enforce them. + Fixes #1695 reported by Korda. + - Normalize the request line in intercepted requests to make rewriting + the destination more convenient. Previously rewrites for intercepted + requests were expected to fail unless $hostport was being used, but + they failed "the wrong way" and would result in an out-of-memory + message (vanilla host patterns) or a crash (extended host patterns). + Reported by "Guybrush Threepwood" in #1694. + - Enable socket lingering for the correct socket. + Previously it was repeatedly enabled for the listen socket + instead of for the accepted socket. The bug was found by + code inspection and did not cause any (reported) issues. + - Detect and reject parameters for parameter-less actions. + Previously they were silently ignored. + - Fixed invalid reads in internal and outdated pcre code. + Found with afl-fuzz and AddressSanitizer. + - Prevent invalid read when loading invalid action files. + Found with afl-fuzz and AddressSanitizer. + - Windows build: Use the correct function to close the event handle. + It's unclear if this bug had a negative impact on Privoxy's behaviour. + Reported by Jarry Xu in #891. + - In case of invalid forward-socks5(t) directives, use the + correct directive name in the error messages. Previously they + referred to forward-socks4t failures. + Reported by Joel Verhagen in #889. + +- General improvements: + - Set NO_DELAY flag for the accepting socket. This significantly reduces + the latency if the operating system is not configured to set the flag + by default. Reported by Johan Sintorn in #894. + - Allow to build with mingw x86_64. Submitted by Rustam Abdullaev in #135. + - Introduce the new forwarding type 'forward-webserver'. + Currently it is only supported by the forward-override{} action and + there's no config directive with the same name. The forwarding type + is similar to 'forward', but the request line only contains the path + instead of the complete URL. + - The CGI editor no longer treats 'standard.action' special. + Nowadays the official "standards" are part of default.action + and there's no obvious reason to disallow editing them through + the cgi editor anyway (if the user decided that the lack of + authentication isn't an issue in her environment). + - Improved error messages when rejecting intercepted requests + with unknown destination. + - A couple of log messages now include the number of active threads. + - Removed non-standard Proxy-Agent headers in HTTP snipplets + to make testing more convenient. + - Include the error code for pcre errors Privoxy does not recognize. + - Config directives with numerical arguments are checked more carefully. + - Privoxy's malloc() wrapper has been changed to prevent zero-size + allocations which should only occur as the result of bugs. + - Various cosmetic changes. + +- Action file improvements: + - Unblock ".deutschlandradiokultur.de/". + Reported by u302320 in #924. + - Add two fast-redirect exceptions for "yandex.ru". + - Disable filter{banners-by-size} for ".plasmaservice.de/". + - Unblock "klikki.fi/adv/". + - Block requests for "resources.infolinks.com/". + Reported by "Black Rider" on ijbswa-users@. + - Block a bunch of criteo domains. + Reported by Black Rider. + - Block "abs.proxistore.com/abe/". + Reported by Black Rider. + - Disable filter{banners-by-size} for ".black-mosquito.org/". + - Disable fast-redirects for "disqus.com/". + +- Documentation improvements: + - FAQ: Explicitly point fingers at ASUS as an example of a + company that has been reported to force malware based on + Privoxy upon its customers. + - Correctly document the action type for a bunch of "multi-value" + actions that were incorrectly documented to be "parameterized". + Reported by Gregory Seidman on ijbswa-users@. + - Fixed the documented type of the forward-override{} action + which is obviously 'parameterized'. + +- Website improvements: + - Users who don't trust binaries served by SourceForge + can get them from a mirror.
